Lineage: Bifidobacterium adolescentis; Bifidobacterium; Bifidobacteriaceae; Bifidobacteriales; Actinobacteria; Bacteria
General Information: Human gut bacterium. This species is a normal inhabitant of the healthy human gut. Newborns, especially those that are breast-fed, are colonized with Bifidobacteria within days after birth. This species was first isolated from the feces of a breast-fed infant. In one comprehensive 16S rDNA sequence-based enumeration of the colonic microbiota of three healthy adult humans it represents, on average, 0.008% of all 16S rDNA sequences and 4.302% of the sequences in its division (Eckburg et. They are saccharolytic organisms that produce acetic and lactic acids without generation of CO2, except during degradation of gluconate.
Subject: NC_006177:12383 Symbiobacterium thermophilum IAM 14863, complete genome
Lineage: Symbiobacterium thermophilum; Symbiobacterium; Shewanellaceae; Clostridiales; Firmicutes; Bacteria
General Information: This symbiotic and thermophilic bacterium was discovered by screening for thermostable tryptanophases in Japanese compost. Cultured growth of this organism requires the presence of another bacterial species, such as a Bacillus or Escherichia coli, which provides diffusable metabolites required for its growth. Pure cultures can be obtained by growing Symbiobacterium thermophilum in a bioreactor, separated from its symbiotic counterpart by a dialysis membrane. Because of its symbiotic nature, it cannot be cultured with conventional methods. Despite a negative reaction for gram stain, this species is placed with the gram-positive bacteria based on 16s phylogenetic analysis.
